I trust these the least- my mum was ambushed by one of these in MK as she was eating a musli bar. It ENDED UP HANG OFF HER FINGER and a CM came to here rescue- It drew blood, she had to go to the first aid room to get it cleaned up. Only on our return did we find out from our GP that she should have had a rabies shot but the lady at first aid had said this was not needed even although I asked about it

Anyway it was 9 yrs ago so she more or less in the clear now. Since then we always eat nut free outdoors in Florida just incase
